PRODUCTS DESCRIPTION:
Annealed Wire is made of carbon steel wire, used for weaving,
baling in general. Applied for home use and the construction.
Annealed wire is obtained by means of thermal annealing, endowing
it with the properties it needs for its main use - setting. This
wire is deployed both in civil construction and in agriculture.
Hence, in civil construction annealed wire, also known as "burnt
wire" is used for iron setting. In agriculture annealed wire is
used for bailing hay.
Annealed wire for civil construction:
The annealing of bare wire (wire which has simply been drawn) can
be carried out in batches (bell-type furnace) or in line (in-line
furnace).
Annealing is intended to return to the wire its ductility which it
had lost during drawing.
Annealed wire is stored in coils or spools of a varying weights and
dimensions depending on the purposes for which it is intended and
the needs of clients. The product does not usually have any type of
protective lining, paper or plastic. We offer two kinds of annealed
wire, bright annealed and black annealed wire. Black annealed wire
gets its name from its plain black color.
Soft annealed wire offers excellent flexibility and softness
through the process of oxygen free annealing.
Packing: Spools, coils.
